Application filed. February 23, 1923. Serial No. 620,831.

To all whom it may concern: Be it known that I, Fonnnsr E. CAnnULLo, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented Improvements in Housings for Planers. of which the following is a full, clear, and exact description, reference being had to the accompanying drawing, forming part of this specification.

My invention relates to metal planers and has to .do with methods of attaching the saddle for the side head, and the cross rail, to the housings.

The purpose of this invention is to provide a more secure and free moving attachment for the side head saddle, and to secure a more rigid method of attaching the cross rail, whereby the thickness of the rail where it is subject to bending and torsion is increased, and the length of that portion of the rail subjectto such action is diminished.

Among other things a standard or housing is provided in which the form of groove therein is designed to accommodate both the side head and the rail in the advantageous manner noted. 1

I accomplish my objects by that certain construction and arrangement of parts to be hereinafter more specifically pointed out and claimed.

In the drawings:

Figure 1 is a section through the h0usings of a planer above the cross rail, taken in a horizontal plane.

Figure 2 is a section through one of the planer housings and the saddle of a side head, also taken in a horizontal plane.

Figure 3 is a front elevation partially diagrammatic of a planer, showing the location of the frame parts involved in this invention.

Referring to the drawings, a is a portion of the right hand, and b is a portion of the left hand, housing of a planer. 0 is the saddle of a side head which slides vertically upon the front face of the housing at, below the rail. in order toinsure true and accurate motioh of the saddle c, and to keep it from springing away from the housingat any point, under the action of the working forces, it is formed with a hook or dovetail projection c which fits into a corresponding dovetail groove formed at the inner edge of the ffront- {t'aee of the housing. The faces of this groove are a and a, and the saddle c is held in firm sliding contact with these faces by means of a gib d which abuts against surface a The surface a is a smoothly machined surface formed in the groove (1." and parallel with the intersection of surfaces a and a Surface of is slightly relieved so that there is clearance between the housing and the saddle at this surface.v The saddle is held in firm sliding contact with the housing face at a by means of the gib e which'engages the surface. a machined on the rear of a tongue or ledge formed at the outer edge of the housing face. This ledge is bounded by surfaces a, a and a Gib e is held in place by clamp f which is fastened to the saddle by stud g and nut h. This construction enables .me to hold saddle 0 in firm sliding contact with housing. a at the extreme inner and outer edges of the housing face, so that it can notspring away from the housing face when working forces are applied to it. At the same time by placing gib d so that it is in contact with surface a instead of with surface a, the saddle is guided in a vertical direction much more easily, since the two guiding surfaces a and a are much closer together.

The groove included between a and a is designed also to acconnnodate the cross rail in the manner to be noted, and thus a single housing construction doing double duty is provided, which housing provides advan tageons mounting possibilities for the saddle and the rail as well.

Between the housings a and 7) is cross rail This cross rail instead of being of usual form is ln'ovided with two step-like projections i and i which bear against faces c and b of the dovetail gioovcs formed in housings a and b. At the inner side of each housing is a tongue or ledge by means of which the rail is clamped to the housing. On one side of each of these ledges is machined a clamping surface a and Zr. Against these clamping surfaces bear clamps j and 70, held tightly in place by studs Z and m, and nuts n and 0. The rail is thus clamped tightly to the ledge,the rail hearing against surfaces (1 and b and the clamps against the surfaces a and 5 My improvements consist in proi iding the projections i and 6 by means of which the housings. Furthermore the thickness of the rail at the point of clai'nping is increased from the thickness indicated. by the line D to the thickness indicated by the line C, and the rail thereby made much stronger as well as stiffer.

Having thus described my invention, what .i claim as new and desire to secure by Letters Patent, is

1. In a metal. planer, a vertical housing having a dovetail groove formed at the inner edge of the face thereof and a bearing surface machined in a second groove in the face of the said housing and parallel with the said dovetail groove, a saddle adapted to slide upon the said l'iousing and having a dovetail projection adapted to engage thesaid dovetail groove, and a. gil) sliding with the saddle upon the said machined surface, and adapted to d any the dovetail pro ectlon of the saddle into firm sliding contact with the said dovetail groove .2. In a metal planer, a vertical housing having a dovetail groove 'orined at the inner edge of the face ther: i and a bearing surface machined in a sccoi d groove in the front face of the said housing and parallel with the said dove-tail groove, a saddle adapted to slide upon the said housing and having a dove-tail projection adapted to engage the said dove-tail groove, a gib sliding with the saddle upon the said machine surface. and adaptcd lo draiv the dove-tail projection of the saddle into lii'm :jaliding contact with the said dove-tail groove, and a second gib sliding with the saddle and adapted to draw the saddle into lirni-sli ling contact with thefi ontfamwoEllie housing near its out?!" ed ge.

fl. In a metal planer, a vertical housing l'niving a dove-tail groove formed at the inner edge of the face thereof whereby the housing is adapted to receive the dovetail of a sliding saddle, a cross rail having a step lilie projection one face of which is adapted to engage one face of the said dove-tail groove and a clamp on the cross rail engaging the lniusing at a point thereon which ing a housing having a dove ail groove along the inner edge of the face thereof, a side head having a dove-tail projection to fit said groove, and a cross rail having projection adapted to lie against the one face of the dove-tail groove only, and the groove so cut, that it removes part of the corner of the housing, whereby said projection on the cross rail does not dovetailinto the said groove.

5. A housing for planers and a cross rail associated therewith, comprising a housing having a groove cut in the inner edge of the face thereof, said groove removing part of the adjacent corner of the housing, a cross rail, bearing against the housing, and having a projection engaging the one face of said groove, and a clamp on the cross rail engaging the housing at a point thereon which pulls the cross rail bearing on the groove into tighter engagement therewith.

6. A housing for planers and across rail associated therewith, comprising a housing having a projecting ridge extending along its inner face and having a bearing face di rected substantially parallel with the cross rail, and a cross rail having a pro ection to he along said parallel bearing face, and. o

With. said bearing face and to engage the inner face of said houslng pro ection, and a clamp on the cross rail adapted to engage the housing at another point in a direction opposing the said bearing face, whereby the said projection of the housing is engaged at one side by the clamp and at the other by the cross rail.

7. A housing for planers, and a side head and cross rail associated therewith, comprising a housing having a dov tail groove along the inner edge of the face thereof, a side head having a dovetail projection to fit said groove, and a cross rail having a projection adapted to lie against one/ face of the dovetail. groove on'y, and thegroove so cut, that it removes part of the corner of the housing, whereby said projection on the cross rail. does not dovetail into the said groove, and means on the rail and side head to engage the housing at another point to maintain their respective engagements with said groove.
